使用版本知悉

limengjiedeMacBook-Pro:~ limengjie$ python --version

Python 3.6.4 :: Anaconda, Inc.

limengjiedeMacBook-Pro:~ limengjie$ python -m django --version

1.11.13

 

工作需求是1.11.13（安装时，pip版本较低，2.0以下版本安装会超时，2.0以上版本安装正常）

mac环境下，安装Django 2.0以下版本报错

使用pycharm安装异常截图

使用命令行安装，异常如下

You are using pip version 9.0.1, however version 10.0.1 is available.

pip install django==1.11.13 报错源码

解决方案：

You are using pip version 9.0.1, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

按照提示，更新pip版本后，安装正常

安装成功验证：

方法一：

>>> import django
>>> print django.VERSION # Python2的格式  
>>> print(django.VERSION) # python3版本
(1, 11, 13, 'final', 0)

方法二：（也是通过查看版本号，python -m django --version）

limengjiedeMacBook-Pro:~ limengjie$ python -m django --version
1.11.13
